Ordered new 20” wheel with +48mm offset from Tirerack

[Adventusaurus]

Bolt Patterns: 5x120

The link I posted was to a generic one for weight rating. The bolt pattern from tirerack is correct for the Rivian.

Also following. Hopefully this all works out. Keep us updated @Adventusaurus !

I've been back and forth with TireRack on this same wheel for a winter tire set. I've had very good experiences with their customer service over the years - very knowledgeable and super responsive with any issues.

And also make sure you get the proper wheel centering rings. Not having the proper centering ring will cause all kinds of problems with wheel balance and weight distribution when wheels are installed on the car.

These wheels are hub centric. Rings aren't needed for installation according to Tire Rack

So the rims came already. They are actually stamped Fondmetal 9XR. No weight rating on the box, but per the web weight rating is 2000lb. https://www.mrwheeldeal.com/buy-whe...fondmetal-9xr-20x9-45?suspension=Leveling+Kit

Should be sufficient for my winter mountain trips. Probably not ideal for off roading or towing.

Per tirerack they are 2500lbs

Per tirerack they are 2500lbs

Funny you say that... I just got an email saying it's 3,014. Either way it's a good thing both numbers are more than what's needed.

Ha.
Here is a quote from the email I got:
The MSW is 2535lbs per wheel.
The Radius is 2480lbs per wheel

I haven't yet seen a picture of the MSW Type 52 wheel; nor a price as it happens. The Radius in silver looks like it'll work; and if something goes wrong, TireRack is a solid outfit.

Do you need a hub ring?

According to the tire rack (just chatted with them), the wheel is also 64.1 so no ring needed
That is actually awesome if true!

I was told the same thing by Tire Rack.

Yes - I was told the same.

Following this thread to see the results. Basically, will wheels clear calibers, and will they have any rubbing under the low/lowest setting...

 

[Adventusaurus]

Sorry folks been a little swamped. My tpms and tires have arrived today. Will probably be next week when I can get the tires mounted. Am fairly confident the wheels will clear the calipers, but will try one out over the weekend if I have time and confirm.

Much happier if the rating is 2500lb - gives a bit of buffer. 2000lb seemed kinda borderline. Thanks for contacting tire rack.

Measured the center bore with my cheapo calipers. Does appear to be roughly 64mm so great news there. Took a few photos of some of the markings, and also the backside of the wheel. You can see from the backside the clearance to the calipers looks like it will be fine.

Also tried the Rivian center caps that fit the oem 21” wheel, and they are too small so those won’t work, unfortunately.

Center bore measurement.

Supplied Lug nuts.

Fondmetal marked on front

View from rear looks promising for clearing the calipers. Spokes could not really be any more out of the way.

.
Rear marking - 9Jx20H2

Front marking "made in Italy"

Front marking 9XR

rear marking 9xr/18-A. Presumably 18-A is the sub-model.

How far off is it?
As in: would a 3D printed adapter work, do you think?

I ended up ordering a set of these with K02s already mounted. Tirerack doesn't have the TPMS for Rivians yet so I'm going to run without them at first. Supposed to be taking the truck off-road this weekend, so good excuse to order. Should be here today.

Photos installed and when you get out there, please and thank you!
